The integrated control device has the following automatic and manual control processes:
1. and connecting and installing pipelines.

When the liquid level in the buffer container rises to the upper liquid level switch position, the upper liquid level switch and the lower liquid level switch both output high-level signals to the relay, the relay drives the electromagnetic valve for closing the gas, and simultaneously, the electromagnetic valve for opening the liquid is used for discharging the liquid; when the liquid level in the buffer container drops to the position of the lower liquid level switch, the upper liquid level switch and the lower liquid level switch both output low-level signals to the relay, the relay drives to close the electromagnetic valve for liquid, and after the air pressure in the buffer container rises to the injection pressure, the relay drives to open the electromagnetic valve for air, so that air is injected into the injection pipeline.
4. And (5) manual control. During operation of the integrated device, the liquid level can be observed through a liquid level window of the panel of the device, and the electromagnetic valve is manually opened or closed through a panel button. For example, the electromagnetic valve for gas can be closed manually, and then the electromagnetic valve for liquid is opened to drain liquid; after the liquid discharge is finished, the electromagnetic valve for liquid is manually closed, the electromagnetic valve for gas is manually opened after the air pressure in the buffer container is stable, and the gas injection is recovered.

When the liquid level in the buffer container 5 is discharged below the lower liquid level switch 8, the upper liquid level switch and the lower liquid level switch are both low-level signals, and at the moment, the liquid electromagnetic valve 14 is closed; when the air pressure rises to the injection pressure, the air solenoid valve 12 is opened to resume the injection.
In the running process of the integrated device, the gas flow is automatically regulated by a flow signal controller; the high-low level trigger relay is utilized to logically control the opening and closing of the electromagnetic valve through the combination of high-low level signals given by the upper liquid level switch and the lower liquid level switch; when the air pressure is larger than the injection pressure, the air-used pilot electromagnetic valve of the air outlet pipeline can be utilized to enable the internal components to act, and the electromagnetic valve is opened under the control of the high-low level trigger relay, so that the phenomenon that liquid flows back due to the opening of the electromagnetic valve when the air pressure is relatively low can be avoided.
